Hello everyone,I want to learn latin vocabulary systematically on the basis of proto-indo-european roots.The source/book should list pie roots and latin words derived from them, including words derived by addition of further affixes. .....Manfred

You already have some wise answers, yet you or your readers should realize that it would take many years for you to say in Latin, " Then the wolf said to the lamb: since you mud my water, I have to eat you up." Or you can reconstruct Aesop's fable, which was retold in Latin as "Lupus et Agnus". To go from these two words to the proposed sentence: Deinde agno lupus dixit...., you must learn how to specify who is speaking to whom by studying some available grammar. The Indo-European roots will not tell you how "loqui latine" [to speak Latin]. Good luck.
